Heat Exchanger Tubes
Seamless cold-finished tubes in the size range 6,0 up to 60,3 mm OD particularly in Heat exchanger and condenser tubes (pipes) dimensions can be supplied in fix- and random lengths, in straight lengths as well as in U-bend execution. seamless tubes in stainless steel, nickel alloys and titanium as mentioned are applied in Chemical industry, Petrochemical industry, Fertilizer industry, Power industry, Thermal Processing Plants and Shipbuilding Industry all over the world. Even when applied under most severe operating conditions Seamless Tubes have proved that they meet highest requirements in respect to quality, performance and resistance.
